Controlled expansion of an intravaginal device can be achieved by selectively attaching either a primary or secondary cover to the primary absorbent device having a fluid storage element, we can determine that certain portions of the tampon will expand while other portions will be restricted to substantially the compressed structure. The primary cover can be attached to the primary absorbent device either before or after the absorbent device is compressed into final tampon form. The compression may be in the axial or radial direction or a combination of both directions. The secondary cover, if used, can be attached after the tampon pledget has been compressed into the final tampon form.

Selon l'invention, on peut réguler l'expansion d'un dispositif intravaginal en fixant sélectivement au dispositif absorbant principal un élément de recouvrement principal ou secondaire comprenant un élément de stockage de liquide. On peut ainsi faire en sorte que certaines parties du tampon subissent une expansion alors que d'autres restent sensiblement limitées à la structure comprimée. L'élément de recouvrement principal peut être fixé au dispositif absorbant principal avant ou après la compression en une forme de tampon finale. La compression peut être réalisée dans le sens axial ou radial ou une combinaison de ces sens. L'élément de recouvrement secondaire, le cas échéant, peut être fixé après la compression en une forme de tampon finale.
